Description

Power transmission device magnetic

Field of the Invention

The present invention relates to a system of magnetic power transmission to transmit a force of actuation between a plurality of elements by forces magnetic

Background of the invention

Conventionally, as a system of Magnetic power transmission of this type, the described in patent literature 1. This system of Magnetic power transmission consists of a plurality of magnetic gears and a system body. Each gear magnetic includes a magnetic disk formed of a material magnetic, a magnetic ring ring mounted on a surface of the magnetic disk using an adhesive, and a rotation axis snapped into a central portion of the magnetic disk. He axis of rotation is rotatably supported by the system body. He magnetic toothed ring is a set of a flat device and annular large number of magnetic teeth each formed by a permanent magnet and arranged so that the magnetic teeth are of different polarity between each two adjacent. In addition, each magnetic tooth has a radiation curve shape, such as a form of curve involves.

In the power transmission system magnetic, a pair of magnetic gears are arranged such so that its surfaces on the side of the magnetic toothed ring face each other, and the respective portions of the surfaces of the gear teeth magnetic rings magnetic overlap with each other with a predetermined distance between the rings of magnetic teeth. A magnetic force acts between the overlapping portions, so that torque is transmitted between the pair of magnetic gears. Since the pair is transmitted thus by magnetic force, compared to a power transmission system arranged to transmit torque by mechanical contact, the previous transmission system of magnetic power is advantageous because no structure is needed lubricant, and there is no danger of occurrence of slack or generation of dust in the contact portions.

Patent Literature 1: Patent Publication Japanese (Kokai) number 2005-114162.

Japanese Patent Publication Number 59 023155, which represents the closest prior art, describes how to effectively use force by using a magnet and for the simultaneous combined use of repulsion and attraction. Since a fixed magnet on the side wall side and a magnet of pole inversion make contact with each other to polarities different from each other, an N pole and an S pole are depolarized inside, and only one S pole and one N pole outside are independently in a repulsion relationship. A fixed magnet and a pole reversal magnet on the rotating shaft side are also placed in the relationship in which the attraction is exercised only between its two outer poles. In one position, the attraction between poles are exercised in the upper, and simultaneously, repulsion between the poles is exercised in the lower one, giving rise to the creation of a force of repulsion. In a position a force of attraction 4, which is total attraction minus total repulsion, in a position C, a repulsive force 4 is exerted analogously, in a position D an attractive force 4 is exerted so analogous, and this causes these forces, in order, to rotate an axis rotary. The greater the number of such magnets arranged, the greater the number of the poles, which contact different polarities and depolarize, and the number of poles, which contact each other at the same polarity and are independent, and repulsion and attraction are great, giving rise to the possibility of saving Energy.

Description of the invention

According to the power transmission system conventional magnetic described above, it transmits torque between the pair of the magnetic gears by the magnetic force that acts in the overlapping portions of the magnetic tooth rings, so that the ratio of a portion that contributes to the torque transmission to a total area of each toothed ring magnetic is so small that it is impossible to ensure efficiently an area of a magnetic path. This results in a low torque transmission efficiency and a small capacity of torque transmission In addition, magnetic teeth have a shape so complicated that it makes its manufacturing annoying and slow, which increases the manufacturing cost of the transmission system of magnetic power

The present invention has been made with that of provide a solution to the problems described above, and their object is to provide a power transmission system magnetic that is able to improve the transmission efficiency of power and power transmission capacity and reduce the system manufacturing costs, while maintaining advantageous effects of power transmission performed by magnetic forces

when every first magnetic pole and every second magnetic pole in the first opposite position have polarities different from each other, every third magnetic pole and every fourth magnetic pole in the second opposite position have polarities identical to each other; when every first magnetic pole and every second magnetic pole in the first opposite position have identical polarities to each other, every third magnetic pole and every fourth magnetic pole in the second opposite position have polarities different from each other, and where when each first pole magnetic and every second magnetic pole are in the first opposite position, if each first element of magnetic material soft is in a position between the first magnetic pole and the second magnetic pole, every second element of magnetic material soft is in a position between two pairs of third poles magnetic and fourth magnetic poles adjacent to each other in the default address, and if every second item of material soft magnetic is in a position between the third pole magnetic and the fourth magnetic pole, each first element of soft magnetic material is in a position between two pairs of first magnetic poles and second magnetic poles that are adjacent to each other in the default direction.

According to this power transmission system magnetic, the second mobile element and the fifth mobile element are arranged so that they are relatively mobile along of the default address with respect to the first item mobile and to the first and second mobile elements, respectively, and the fourth mobile element and the sixth mobile element are arranged so that they are mobile along the direction default with respect to the third mobile element and the third and fourth mobile elements, respectively. In addition, the third and fourth mobile elements move relative to first and second moving elements, respectively, so nestled, and the sixth mobile element moves relative to the fifth mobile element interlocked, and therefore if any of the mobile elements first to sixth is fixed to an element default arranged so that it is still other than first to sixth mobile elements, an element embedded in the mobile element interlocked with the fixed mobile element is also fixed immovably (it should be noted that throughout the memory descriptive, "move along a predetermined direction" it is meant to move both in one direction and in one opposite direction to the first direction, along a default address, as in the case where "move along from a left-right direction "means move in the directions both to the left and to the right). In addition, "the third mobile element moves in relation to the first mobile element in an interlocked way "it means that the first mobile element and the third mobile element are in a mutually embedded relationship in which each one moves according to the other).

First, a case will be described where the first mobile element is fixed, and the driving force is introduced to the second mobile element, so the second moving element is moved, for example, along the direction Default in your address. In this case, the first element mobile is fixed, so the third mobile element interlocked with him it is also fixed, and in a way nestled with the second mobile element, the fourth mobile element also moves. Before the start of the movement of the second and fourth moving elements, in a state where every first magnetic pole and every second pole magnetic in the first opposite position have polarities different from each other, if each first soft magnetic element is between the first magnetic pole and the second magnetic pole, it generate lines of magnetic force (named below "the first lines of magnetic force") between these first magnetic poles, first elements of soft magnetic material, and second magnetic poles, and the length of the first lines of magnetic force is shorter, and the total amounts of its Magnetic flux are bigger.

Moreover, in the state where the first soft magnetic element is between the first magnetic pole and the second magnetic pole, every third magnetic pole and every fourth magnetic pole in the second opposite position have the same polarity, and every second element of soft magnetic material is in a position between two pairs of third magnetic poles and fourth magnetic poles adjacent to each other in the direction default, so that lines of magnetic force (referred to below as "the second lines of force magnetic ") generated between the third magnetic poles, the second elements of soft magnetic material, and the rooms Magnetic poles have a large degree of curvature, approximately the maximum length, and approximately the minimum total amounts of magnetic flux (indicate that throughout the present specification, "the first pole magnetic and the second magnetic pole are in an opposite position one to another "is not limited to the respective centers of the two poles are in the same position in the default direction, but includes that the respective centers of the two poles are in a positional relationship where they are slightly displaced one of other).

From the previous state, when the second moving element begins to move in one direction by the force of drive, increases the degree of curvature of the first line of magnetic force In general, the magnetic force line has a characteristic that, when curved, generates a force magnetic that acts to shorten its length, and therefore, when the first line of magnetic force curves as it has described above, a magnetic force that acts on the first Soft magnetic material element is larger as the degree of curvature of the first line of magnetic force is greater, and as your total amount of magnetic flux is greater. Plus specifically, the magnetic force that acts in the first Soft magnetic material element has a characteristic that It is determined depending on the synergistic action of the degree of curvature of the first line of magnetic force and the amount Total magnetic flux.

Therefore, when each first element of soft magnetic material starts to move from between each first magnetic pole and every second magnetic pole, the length of the first line of magnetic force is short with a lot total of its magnetic flux, and the first line of magnetic force begins to bend, so that a strong magnetic force acts in the first element of soft magnetic material per action synergistic of the degree of curvature of the first line of force magnetic and the total amount of its magnetic flux, so the fifth mobile element is moved in the same direction as the direction of movement of the second mobile element. On the other hand, when the second mobile element begins to move as it has described above, the fourth mobile element moves so nestled with the second mobile element, so every room magnetic pole moves away from the second opposite position where it is opposite to every third magnetic pole that has the same polarity, to move towards each third magnetic pole that is adjacent to every third magnetic pole that has the same polarity, and has a polarity different from that of the fourth magnetic pole. According to this movement, second lines of magnetic force are generated between the third magnetic poles, the second material elements soft magnetic, and the fourth magnetic poles. Although the grade of curvature of each second line of magnetic force be large, the total amount of its magnetic flux is small, so that a relatively weak magnetic force act on the second element mobile for its synergistic action. This moves the sixth mobile element in the same direction as the direction of movement of the room mobile element.

So when the second mobile element is move more, even if the degree of curvature of each first one increases magnetic force line, the total amount of its magnetic flux decreases, so that the magnetic force acting on the first soft magnetic material element decrease by its action synergistic to reduce the driving force of the fifth mobile element. When each first magnetic pole moves to the first position opposite to each second magnetic pole that has the same polarity, each first element of soft magnetic material it becomes between two pairs of first magnetic poles and second magnetic poles adjacent to each other in the direction default Consequently, although the degree of curvature of The first line of magnetic force is large, the total amount of its magnetic flux is approximately minimal, and its action synergistic causes the magnetic force to act in the first Soft magnetic material element be approximately the most weak, so that the driving force acting in the fifth Mobile element is approximately smaller.

Moreover, when the second mobile element moves as described above, the fourth element mobile moves interlocked with the second mobile element, and every fourth magnetic pole moves in such a way that it is more next to every third magnetic pole that has a polarity different. This makes every second line of magnetic force less in its degree of curvature, but greater in the total amount of magnetic flux so that the magnetic force acting in the second element of soft magnetic material is increased by its synergistic action, to increase the driving force of the sixth mobile element. When every third magnetic pole moves to a position near the second opposite position where you are in front of every fourth magnetic pole that has a polarity different from its polarity, the second line of magnetic force is larger in the total amount of its magnetic flux, and it curves by a movement of the second element of soft magnetic material following the fourth magnetic pole with a slight delay of speed. As a result, its synergistic action makes approximately stronger the magnetic force that acts on every second element of soft magnetic material, which makes the force of drive that acts on the sixth mobile element be approximately larger.

As described above, when the second moving element moves more in one direction from the state in which the driving force acting in the fifth mobile element is almost minimal, and at the same time the strength of drive that acts on the sixth mobile element is almost maximum, conversely to the above, the first lines of magnetic force they decrease in their degree of curvature, and increase in the amounts totals of its magnetic flux, so that its synergistic action makes stronger the magnetic forces acting in the first soft magnetic material elements to increase the strength of actuation of the fifth mobile element. On the other hand, the second lines of magnetic force increase in their degree of curvature, and decrease in the total amounts of its flow magnetic, so that its synergistic action weakens the forces magnetic that act on the second material elements soft magnetic, and decreases the driving force of the sixth mobile element.

As described above, the elements fifth and sixth mobiles are moved, along with the movement of the second mobile element, while repeating alternately a state in which the driving force acting in the fifth mobile element increases and the driving force acting on the sixth mobile element decreases, and a state in which the force of drive acting on the fifth mobile element decreases and the driving force acting on the sixth mobile element increases, so that it is possible to transmit the force of drive introduced in the second mobile element to the fifth and sixth mobile elements. In addition, the fourth mobile element has been arranged so that it moves relative to the second mobile element interlocked, and therefore even when the driving force is introduced into the fourth element mobile, the driving force can be transmitted to the fifth and sixth moving elements, as described previously.

In addition, while every second magnetic pole of the second moving element moves from a first opposite position to each first magnetic pole that has a different polarity from its polarity at a first position opposite each first pole magnetic that has the same polarity, each first element of soft magnetic material moves from the first position opposite a position between two pairs of first magnetic poles and second magnetic poles adjacent to each other in the direction default Therefore, the fifth mobile element moves in a more decelerated state than the second mobile element. Equally, while each fourth magnetic pole of the fourth mobile element is moves from a second opposite position where it is facing every third magnetic pole that has a different polarity from its polarity, to a second opposite position in which you are facing of every third magnetic pole that is adjacent to the third pole magnetic and has the same polarity, every second element of soft magnetic material moves from the second position opposite a position between two pairs of third magnetic poles and fourth magnetic poles adjacent to each other in the direction default Therefore, the sixth mobile element moves in a been more decelerated than the fourth mobile element. That is, the driving force introduced in the second mobile element or the fourth mobile element can be transmitted to the elements fifth and sixth phones in a decelerated state.

A case will be described below where, conversely to the above, the second mobile element is fixed, and the driving force is introduced in the first element mobile. In this case, for that reason, the fourth mobile element it is also fixed, and the third mobile element is also moved from way interlocked with the movement of the first moving element moved by the driving force. So the moving elements fifth and sixth are moved along with the movements of the first mobile element and the third mobile element, as described above, while repeating alternately a state in the that the driving force acting on the fifth element mobile is increased and the driving force acting on the sixth mobile element is diminished, and a state in which the force drive acting on the fifth mobile element is decreased and the driving force acting on the sixth mobile element is increases As a result, the driving force introduced in the first mobile element it can be transmitted to the elements fifth and sixth mobiles. In addition, as described above, the fifth mobile element slows down more than the first element mobile, and the sixth mobile element also slows down more than the third mobile element, so that the driving force introduced in the first mobile element or the third mobile element it can be transmitted to the fifth and sixth mobile elements in a decelerated state.

A case will be described below where the fifth mobile element is fixed, and the driving force is introduced in the first mobile element. In this case, by said reason, the sixth mobile element is also fixed, and the third mobile element also moves interlocked with the movement of the first mobile element. Before the start of movement of the first mobile element, when each first pole magnetic and every second magnetic pole that has the same polarity are in the first opposite position, and every first soft magnetic material element is in a position between two pairs of first magnetic poles and second magnetic poles adjacent to each other, as described above, the degree of curvature of each first line of magnetic force is large and its length is approximately maximum, so that the amount Total magnetic flux is approximately minimal.

From this state, when the first moving element begins to move in one direction along the default address, the first magnetic pole of the first moving element begins to move so that it is closer to the first element of soft magnetic material, and at the same time is closer to the second magnetic pole of the second element mobile that has a polarity different from that of the first pole magnetic, adjacent to the second magnetic pole of the second element mobile that has the same polarity. According to the movement of the first magnetic pole, the first line of magnetic force is changed to make your length shorter and the total amount of your magnetic flux, making at the same time considerably large Its degree of curvature. As a result, a magnetic force acts relatively strong at every second magnetic pole per action synergistic of the total amount of magnetic flux of the first line of magnetic force and its degree of curvature, so the second mobile element is moved so that it is closer to the first mobile element. Nailed to this, the fourth mobile element is also moved in such a way that it is closer to the third mobile element. That is, the second mobile element is moved in a direction opposite to the direction of movement of the first mobile element, and at the same time the fourth mobile element it is also moved in a direction opposite to the direction of movement of the third mobile element.

So when the first magnetic poles they are even closer to the first material elements soft magnetic, the second magnetic poles also move from such that they are closer to the first elements of soft magnetic material, due to magnetic forces generated by the first lines of magnetic force. When every first pole magnetic moves to a position where it is closest to a first element of soft magnetic material, the first pole magnetic is put in the first opposite position where it is in front of the second magnetic pole of different polarity with the First element of soft magnetic material placed in between. In this state, the second element of soft magnetic material is in a position between two pairs of third magnetic poles and fourth magnetic poles adjacent to each other.

From this state, when the first moving element moves more, every third magnetic pole of the third moving element is closer to a second material element soft magnetic, and at the same time it moves in such a way that it is closer to a fourth magnetic pole of the fourth moving element that It has a different polarity than the third magnetic pole, adjacent to the fourth magnetic pole of the fourth mobile element that It has the same magnetic pole. According to the movement of the third pole magnetic, the second line of magnetic force is changed to make your length shorter and the total amount of your magnetic flux, making at the same time considerably large Its degree of curvature. As a result, a magnetic force relatively strong acts on every fourth magnetic pole by the synergistic action of the total amount of magnetic flux of the second line of magnetic force and its degree of curvature, so that the fourth mobile element is moved so that it is more next to the third mobile element. Nailed to this, the second mobile element is also moved so that it is more next to the first mobile element. That is, the fourth element mobile is moved in a direction opposite to the direction of movement of the third mobile element, and at the same time the second mobile element is also moved in a direction opposite to the direction of movement of the first mobile element.

As described above, along with the movements of the first and third mobile elements, the second and fourth moving elements are moved in directions opposite to the directions of movement of the first moving element and the third mobile element, while repeating alternately states in which the driving force acts in the second mobile element and the fourth mobile element, respectively, so that it is possible to transmit a driving force introduced in the first mobile element to the second mobile element and the fourth mobile element. In addition, the third mobile element is arranged to so that it moves relative to the first mobile element so interlocked, and therefore even when a force is introduced drive on the third mobile element, the force of drive can be transmitted to the second mobile element and the fourth mobile element. In addition, when each first magnetic pole of the first moving element moves from a position where it is in front of a second magnetic pole that has a polarity different from its polarity to a position where it is facing a second magnetic pole that has the same polarity with the first element of soft magnetic material placed in between, the second magnetic pole of the second moving element also moves the same distance as the distance the first pole moves magnetic. Therefore, the first mobile element and the second moving element move at the same speed, and along with their movements, the third mobile element and the fourth mobile element they also move at the same speed, so that it is possible transmit the driving force introduced in the first mobile element to the fourth mobile element at the same speed.

As described above, according to magnetic power transmission system, if any of the mobile elements first to sixth is fixed and a driving force in another not interlocked with the fixed, by example, if the first mobile element is fixed and a driving force in the second mobile element, the force of drive can be transmitted to fifth mobile elements and sixth by magnetic forces. During the process, you can form magnetic paths using all the first elements of soft magnetic material of the fifth mobile element, all second soft magnetic material elements of the sixth element mobile, and the first to fourth magnetic elements poles first to fourth mobiles that generate lines of magnetic force between them and the soft material magnetic elements, and so both, compared to the conventional transmission system of magnetic power that forms magnetic paths using only part of the magnetic poles, it is possible to improve the efficiency of Power transmission and power transmission capacity, while maintaining the advantageous effects obtained performing power transmission by forces magnetic

On the other hand, also when a driving force in the fifth or sixth mobile element mobile element in a state in which none of the elements first to sixth mobiles are fixed, using the action before described of the lines of magnetic force, it is possible to transmit the driving force to the first magnetic poles of the first moving element and the second magnetic poles of the second element mobile through the first elements of soft magnetic material, and transmit the driving force to the third poles magnetic of the third mobile element and the fourth magnetic poles of the fourth mobile element by the second elements of soft magnetic material. More specifically, the strength of drive introduced in the fifth or sixth mobile element mobile element can be transmitted by dividing the force of actuation in a part transmitted to the first mobile element or the third mobile element and a part transmitted to the second element mobile or the fourth mobile element. Also during the process, such as described above, paths can be formed magnetic using all the first elements of magnetic material  soft of the fifth mobile element, all the second elements of soft magnetic material of the sixth mobile element, and the poles first to fourth magnetic elements of the mobile elements first to fourth that generate lines of magnetic force between them and these magnetic elements of soft material, and therefore, in comparison with conventional power transmission system magnetic forming magnetic paths using only part of magnetic poles, it is possible to improve the transmission efficiency of power and power transmission capacity.

In addition, also when a force is introduced of actuation in the first mobile element and the second element mobile in the state in which none of the mobile elements first to sixth are fixed, using the action described above of the lines of magnetic force, it is possible to transmit the force of drive to the first elements of soft magnetic material by the first magnetic poles of the first mobile element and the second magnetic poles of the second mobile element, and the second elements of soft magnetic material through the third magnetic poles of the third mobile element and the rooms magnetic poles of the fourth mobile element. More specifically, the force resulting from the driving forces introduced into the first mobile element and the second mobile element, respectively, it can be transmitted to the fifth mobile element or The sixth mobile element. Also when doing this, for the reason before described, it is possible to improve the transmission efficiency of power and power transmission capacity.

The invention according to claim 2 is a 1, 1C to 1H magnetic power transmission system according to the claim 1, wherein the first mobile element and the third mobile element are integrally formed with each other as a seventh moving element (outer rotor 11 or inner rotor 12, rotor Small diameter 31 or large diameter rotor 32, left rotor 41 or right rotor 42, outer slide 51 or inner slide 52), the second mobile element and the fourth element being formed integrally mobile with one another as an eighth mobile element (inner rotor 12 or outer rotor 11, large diameter rotor 32 or small diameter rotor 31, right rotor 42 or left rotor 41, inner slide 52 or outer slide 51), being formed the fifth mobile element and the sixth mobile element integrally with each other as a ninth moving element (rotor intermediate 13, intermediate diameter rotor 33, intermediate rotor 43, intermediate slide 53).

According to this power transmission system magnetic, the torque introduced into a rotor can be transmitted to one or both of the two remaining rotors by forces magnetic, so it is possible to make a system of Magnetic power transmission to perform torque transmission. In addition, since the plurality of magnetic poles first to quarters and the plurality of first and second material elements Soft magnetic are made equal in number to each other, it is possible form magnetic paths efficiently using all opposite surfaces of the magnetic poles and the elements soft material magnetic, making it possible to ensure more efficiently the magnetic path zones to pass lines of magnetic force.

As depicted in Figures 1 and 2, the magnetic power transmission system 1 includes a box 10, an outer rotor 11, an inner rotor 12, and an intermediate rotor 13. The case 10 includes a hollow cylindrical body 10a, a gear 10b integrally formed with body 10a, and axes 10c and 10c. He gear 10b is formed so that it extends out of an outer peripheral surface of the body 10a, and is in constant gearing with the transmission gear 4e of the transmission 4. With this arrangement, according to the gear rotation output 4e of automatic transmission 4, box 10 also tour. In addition, axes 10c and 10c, which have a cylindrical shape hollow, extend from the left side surfaces and right of the body 10a, and they are rotatably supported by two bearings 14 and 14, respectively.

On the other hand, the outer rotor 11 includes a axis of rotation 11a, and a pair of left and right discs 11b and 11b formed concentrically on the axis of rotation 11a. Axis of rotation 11a is concentric with the axes 10c of the box 10, and extends to through inner holes of the box 10c, with its end left connected to drive shaft 5. In addition, the disk right 11b is fixed to the right end of the axis of rotation 11a, and the left disk 11b is fixed to a predetermined portion of the axis of rotation 11a with a predetermined disc spacing right 11b.

The left and right disks 11b and 11b are they make an element of soft magnetic material, and in their opposite surfaces, left and right rows of permanent magnets in flat symmetry with each other in positions respective towards outer peripheral ends of the surfaces. The rows of permanent magnets left and right are make up m (m is an integer) permanent magnets 11c, and magnets permanent 11c are mounted on disks 11b in a state arranged so that the opposite magnets of the permanent magnets 11c and 11c have the same polarity. Also, in each row of magnets permanent, permanent magnets 11c are arranged to equally spaced intervals a predetermined distance of such so that its magnetic poles are of different polarity between every two adjacent poles 11c and 11c.

In addition, the inner rotor 12 includes a shaft of rotation 12a concentric with the axis of rotation 11a of the outer rotor 11, and a hollow cylindrical box portion 12b formed concentrically e integrally with the axis of rotation 12a. The axis of rotation 12a has its right end connected to drive shaft 5. In addition, the box portion 12b has a row of permanent magnets arranged at its left end such that the row of magnets permanent be placed in the center between the two rows of magnets permanent of the outer rotor 11 and in front of them. This row of permanent magnets consists of m permanent magnets 12c

Permanent magnets 12c are mounted on the box portion 12b in a state arranged so that the poles magnetic on its left and right sides are polarity different between every two adjacent 12c and 12c. In addition, the magnets permanent 12c have been arranged so that they are in flat symmetry with the permanent magnets described above 11c when the rotor outer 11 and inner rotor 12 are in a ratio of default rotational position. More specifically, magnets permanent 12c are arranged in the same number at the same step and at the same radial distance from the center of rotation as the magnets permanent 11c. In addition, the opposite side surfaces of each permanent magnet 12c have approximately the same area and shape that one end face of each permanent magnet 11c in front of they.

It should be noted that here embodiment, one of the outer rotor 11 and the inner rotor 12 corresponds to the first, third and seventh mobile elements, and the other to the second, fourth and eighth moving elements. Further, the left and right permanent magnets 11c or the magnets permanent 12c correspond to the first and first magnetic poles third, and the others to the second and fourth magnetic poles.

In addition, intermediate rotor 13 rotates in unison with box 10, and includes a hollow cylindrical portion 13a mounted rotatably on the axis of rotation 11a, a left wall 13b that is extends radially from the left end of the portion hollow cylindrical 13a and continuing to the inner wall of the box 10, and a right wall 13c integrally formed with the end right of the hollow cylindrical portion 13a.

A row of left material elements soft magnetic is arranged in a predetermined portion of the left wall 13b such that it is in the center between the left row of permanent magnets of the outer rotor 11 and the row of permanent magnets of the inner rotor 12 in opposite relation to them. The left row of magnetic material elements soft is composed of m left elements of material soft magnetic (for example rolled steel sheets) 13d, and the left elements of soft magnetic material 13d are mounted on the left wall 13b such that they are in flat symmetry with the permanent magnets described above 11c or the permanent magnets 12c when the intermediate rotor 13 is in a default rotational position ratio with the rotor outer 11 or inner rotor 12. More specifically, the left elements of soft magnetic material 13d are arranged in the same number at the same pace and at the same distance radial center of rotation than permanent magnets 11c and permanent magnets 12c. In addition, opposite side surfaces of each left element of soft magnetic material 13d have approximately the same area and shape as the end face of each permanent magnet 11c and opposite side surfaces of each permanent magnet 12c.

On the other hand, a right row of elements of soft magnetic material is arranged at one end of the wall right 13c such that it is located in the center between the right row of permanent magnets of the outer rotor 11 and the row of permanent magnets of the inner rotor 12 in opposite relation to they. The right row of soft magnetic material elements It is composed of m right elements of magnetic material soft (for example rolled steel sheets) 13e. The elements rights of soft magnetic material 13e are arranged in the same number at the same step and at the same radial distance from the center of rotation than the left elements of magnetic material soft 13d, and they are mounted on the right wall 13b in a state circumferentially displaced from the left elements of soft magnetic material 13d half step (see figure 3). In addition, like the opposite side surfaces of each left element of soft magnetic material 13d, the opposite side surfaces of each right element of material soft magnetic 13e have approximately the same area and shape that the end face of each permanent magnet 11c and the opposite side surfaces of each permanent magnet 12c.

In addition, the respective distances between opposite side surfaces of the left element of material 13d soft magnetic, and the opposite end face of the magnet left permanent 11c and the opposite left lateral surface of the permanent magnet 12c, and the respective distances between the opposite side surfaces of the right material element soft magnetic 13e, and the opposite end face of the magnet right permanent 11c and the opposite right side surface of the Permanent magnet 12c are made equal to each other.

It should be noted that here embodiment, the intermediate rotor 13 corresponds to the elements fifth, sixth and ninth mobiles, while one of the elements left and right of soft magnetic material 13d and 13e corresponds to a first element of soft magnetic material, and the another to a second element of soft magnetic material.

In addition, the box described above 10 and three rotors 11 to 13 are supported by large number of radial bearings and thrust bearings (of which none are shown in the figures), so that they hardly change in relationships mutual positions in the direction of the rotational axis and the radial direction, and are arranged so that they are rotating around the same rotational axis in relation to each other.

Next, the operation of the magnetic power transmission system 1 arranged as has previously described. It should be indicated that in the description Next, the rotational speeds of the three rotors 11 to 13 they are represented by V1 to V3, respectively, and the pairs of the three rotors 11 to 13 for TRQ1 to TRQ3. First, it will be described with reference to figures 4 and 5 a case in which the TRQ2 pair is introduced to the inner rotor 12 in a state of the outer rotor 11 fixed non-rotationally (V1 = 0, TRQ1 = 0), so the rotor interior 12 is rotated in a predetermined direction (corresponding  to a downward direction, as seen in figure 4).

First, before the start of the rotation of the inner rotor 12, if the opposite side surfaces of each permanent magnet 12c of the inner rotor 12 is in positions respective opposite to the end faces of the magnets permanent 11c and 11c of the outer rotor 11, the arrangement before described makes one in two pairs of the magnetic poles opposite to each other have different polarities from each other, and that the other of them has the same polarity. For example, as depicted in figure 4 (a), when the pole Magnetic of each left permanent magnet 11c and the magnetic pole at one left end of each permanent magnet 12c they have polarities different from each other, if each left element of 13d soft magnetic material is in a position between these magnetic poles, each right element of magnetic material soft 13e is in a center position between a right pair of permanent magnets 11c and 12c in an opposite position, and a pair right of adjacent permanent magnets 11c and 12c.

In this state, a first line is generated G1 magnetic force between the magnetic pole of each magnet left permanent 11c, each left element of material 13d soft magnetic, and the magnetic pole on the left end of each permanent magnet 12c, and a second magnetic line is generated G2 of force between the magnetic pole of each permanent magnet right 11c, each right element of soft magnetic material 13e, and the magnetic pole at the right end of the permanent magnet 12c, whereby magnetic circuits are formed, as represented in figure 6 (a).

As described above, the line of magnetic force has a characteristic that, when curved, generates a magnetic force that acts to reduce its length, and therefore when the first magnetic line G1 is curved from force, the magnetic force that acts on the left element of 13d soft magnetic material is higher when the degree of curvature of the first magnetic line G1 of force is greater and the amount Total magnetic flux is higher. More specifically, the force magnetic acting on the left element of magnetic material Soft 13d is determined by the synergistic action of the degree of curvature of the first magnetic line G1 of force and quantity Total magnetic flux. Likewise, also in a case where the second magnetic line G2 of force is curved, a force magnetic that acts on the right element of magnetic material Soft 13e is determined by the synergistic action of the degree of curvature of the second magnetic line G2 of force and quantity Total magnetic flux. Therefore, in the state represented in figures 4 (a) and 6 (b), they are not generated magnetic forces that rotate the right material elements soft magnetic 13e up or down, as seen in the figures, by the synergistic action of the degree of curvature of the second magnetic lines G2 of force and the total amounts of its magnetic flux

So when the TRQ2 torque causes the rotor interior 12 rotate from a position shown in the figure 4 (a) to a position represented in Figure 4 (b), according to the rotation of the inner rotor 12, the second magnetic line G2 of force generated between an N pole of a right permanent magnet 11c, a right element of soft magnetic material 13e, and a S pole at the right end of a permanent magnet 12c, or between a S pole of a right permanent magnet 11c, a right element of soft magnetic material 13e, and an N pole at the right end of a permanent magnet 12c, increases in its total amount of flow magnetic, and the first magnetic line G1 of force between a left element of soft magnetic material 13d and the pole magnetic on the left end of a permanent magnet 12c it curve. Thus, the magnetic circuits represented in the Figure 6 (b) by the first magnetic lines G1 of force and the second magnetic lines G2 of force.

In this state, magnetic forces act considerably strong in the left elements of material 13d soft magnetic by the synergistic action of the degree of curvature of the first magnetic lines G1 of force and quantities total of its magnetic flux, and trigger the left elements of soft magnetic material 13d down, as seen in the Figure 4, while relatively magnetic forces act weak in the right elements of soft magnetic material 13e by the synergistic action of the degree of curvature of the second G2 magnetic lines of force and the total amounts of its flow magnetic, and trigger the right elements of magnetic material soft 13e down, as seen in figure 4. As a result, the intermediate rotor 13 is moved such that it rotates therein direction than the direction of rotation of the inner rotor 12, by the force resulting from the magnetic forces that act in the left elements of 13d soft magnetic material and forces magnetic elements that act on the right material elements soft magnetic 13e.

Then, when the inner rotor 12 rotates from the position represented in figure 4 (b) to positions respective depicted in figures 4 (c) and 4 (d), and Figures 5 (a) and 5 (b) in the order indicated, the left elements of soft magnetic material 13d and the Right elements of soft magnetic material 13e are moved down by the magnetic forces generated by the first magnetic lines G1 of force and the second magnetic lines G2 of force, respectively, whereby the intermediate rotor 13 is rotates in the same direction as the direction of rotation of the rotor inside 12. During the rotation of intermediate rotor 13, the magnetic forces acting on the left elements of 13d soft magnetic material are progressively decreased by the synergistic action of the degree of curvature of the first lines magnetic force G1 and the total amounts of its flow magnetic, while the magnetic forces acting on the Right elements of soft magnetic material 13e are progressively increased by the synergistic action of the degree of curvature of the second magnetic lines G2 of force and the total amounts of its magnetic flux.

Then, during the rotation of the inner rotor 12 from the position represented in Figure 5 (b) to a position represented in figure 5 (c), the second lines G2 magnetic forces are curved, and the total amounts of their magnetic flux is near the maximum, so that the forces strongest magnetic of the second magnetic line G2 act in the right elements of soft magnetic material 13e by the synergistic action of the degree of curvature of the second lines G2 magnetic force and total amounts of its flow magnetic. Next, as depicted in the figure 5 (c), when the inner rotor 12 rotates a step P of the magnet permanent 11c to do so that each permanent magnet 12c is move to a position opposite the left permanent magnets and right 11c and 11c, the magnetic pole of each permanent magnet left 11c and the magnetic pole at the left end of each permanent magnet 12c have the same polarity and each element left of soft magnetic material 13d is in a position between the magnetic poles of two pairs of permanent magnets 11c and 12c, each pair having the same polarity. In this state, I don't know generate magnetic forces that rotate the left element of soft magnetic material 13d down, as seen in the figure 5, due to the synergistic action of the degree of curvature of the first G1 magnetic lines of force and the total amount of its flow magnetic. On the other hand, the magnetic pole of each permanent magnet  right 11c and the magnetic pole in the right portion of each magnet Permanent 12c have different polarities from each other.

From this state, when the rotor interior 12 rotates further, the left elements of magnetic material  soft 13d are moved down by generated magnetic forces by the synergistic action of the degree of curvature of the first G1 magnetic lines of force and the total amounts of its flow magnetic while the right material elements soft magnetic 13e are moved down by magnetic forces generated by the synergistic action of the degree of curvature of the second magnetic lines G2 of force and the total amounts of its magnetic flux, whereby the intermediate rotor 13 rotates in the same direction as the direction of rotation of the inner rotor 12. During the process, when the inner rotor 12 rotates to the position represented in figure 4 (a), inversely to the above, the magnetic forces that act on the left elements of 13d soft magnetic material are increased by synergistic action of the degree of curvature of the first magnetic lines G1 of strength and total amounts of its magnetic flux while the magnetic forces that act on the right elements of soft magnetic material 13e diminish by the synergistic action of  degree of curvature of the second magnetic lines G2 of force and the total amounts of its magnetic flux.

As described above, according to the rotation of the inner rotor 12, the intermediate rotor 13 is moved while repeating alternately a state in which the forces magnetic elements that act on the left elements of material 13d soft magnetic are increased and the magnetic forces that act on the right elements of soft magnetic material 13e they decrease, and a state in which the first ones decrease and the latter are increased, so that it is possible to transmit the TRQ2 torque introduced in the inner rotor 12 to the intermediate rotor 13. In this case, when respective pairs transmitted by the left element of soft magnetic material 13d and the element Right of soft magnetic material 13e are represented by TRQ3d and TRQ3e, the ratio between the TRQ3 torque transmitted to the rotor intermediate 13 and the pairs TRQ3d and TRQ3e is generally the represented in figure 7. With reference to the figure, the two TRQ3d and TRQ3e pairs repeat periodic changes, and the sum of TRQ3d and TRQ3e is equal to the TRQ3 torque transmitted to intermediate rotor 13. It is say, TRQ3 = TRQ3d + TRQ3e.

       \ newpage
    

Also, as is evident from the comparison. between figure 4 (a) and figure 5 (c), when the rotor inside 12 rotates a step P of the permanent magnet 11c, the rotor intermediate 13 rotates only half (P / 2) thereof, and so both the intermediate rotor 13 is moved so that it rotates at a value equal to half the rotational speed of the rotor interior 12. This relationship is shown, as represented in the Figure 8 (a), in which V3 = 0.5 x (V2 + V1) = 0.5 x V2. How I know described above, since the rotational speed V3 of the intermediate rotor 13 is reduced to half the rotational speed V2 of the inner rotor 12, the TRQ3 torque transmitted to the rotor intermediate 13 is twice the torque TRQ2 of the inner rotor 12, in the extent to which TRQ3 is within the torque capacity. That is to say, TRQ3 = 2 x TRQ2.

It should be noted that during the rotation of the inner rotor 12 as described above, the rotor intermediate 13 is rotated by the magnetic forces generated by the first magnetic lines G1 of force and the second lines magnetic force G2 pushed by the inner rotor 12, so the intermediate rotor 13 rotates with a small phase delay with with respect to the inner rotor 12. Therefore, when the rotor interior 12 is in the position represented in the figure 5 (c) during its rotation, each left element of material  13d soft magnetic and each right element of magnetic material soft 13e are really in slightly upward positions of the respective positions represented in the figure 5 (c). In Figure 5 (c), however, to facilitate the understanding of the rotational speed described above, the right element of soft magnetic material 13e and the element left of soft magnetic material 13d are represented in the positions illustrated in the figure.

In addition, inversely to the above, in one case where the inner rotor 12 is fixed (V2 = 0, TRQ2 = 0), and the TRQ1 is introduced into the outer rotor 11, according to the rotation of the outer rotor 11, intermediate rotor 13 moves, as has been described above, the state repeats while repeating alternatively a state in which the magnetic forces that act on the left elements of soft magnetic material 13d they increase and the magnetic forces acting on the elements 13e soft magnetic material rights are decreased, and a state in which the magnetic forces acting on the elements left of soft magnetic material 13d are decreased and the magnetic forces acting on the right material elements Soft magnetic 13e are increased. As a result, it is possible transmit the torque TRQ1 introduced in the outer rotor 11 to the rotor intermediate 13.

During the process, for the indicated reason, the intermediate rotor 13 is moved such that it rotates to a value equal to half the rotational speed of the outer rotor 11. More specifically, V3 = 0.5 x (V1 + V2) = 0.5 x V1 (see Figure 8 (b)). In addition, since the rotational speed V3 of the intermediate rotor 13 decreases at half speed rotational V1 of the outer rotor 11, the TRQ3 torque transmitted to the intermediate rotor 13 is twice the torque TRQ1 of the outer rotor 11, to the extent that TRQ3 is within the torque capacity. Is say, TRQ3 = 2 x TRQ1.

It will be described below with reference to the figure 9 a case in which the intermediate rotor 13 is fixed, and the TRQ2 torque is introduced into the inner rotor 12. First, it supposes that before the start of rotation of the inner rotor 12, the three rotors 11 to 13 are in a positional relationship represented in figure 9 (a). From this state, when the pair TRQ2 is introduced and the inner rotor 12 rotates to a position represented in Figure 9 (b), the first magnetic line G1 of force between the left element of soft magnetic material 13d and permanent magnet 12c curves, and at the same time the magnet permanent 12c is closer to the right element of material soft magnetic 13e, so the length of the second line G2 magnetic between the right element of soft magnetic material 13e and the magnetic pole at the right end of the permanent magnet 12c is decreased to increase the total amount of magnetic flux of the second magnetic line G2. As a result, these are formed magnetic circuits shown in figure 6 (b), at referenced above

In this state, although forces are generated magnetic between the left and right material elements soft magnetic 13d and 13e and the magnetic poles at the ends opposite sides of permanent magnets 12c, per action synergistic of the degrees of curvature of the first lines magnetic force G1 and the second magnetic lines G2 of strength and the total amounts of its magnetic flux, have no influence given that the inner rotor 12 is moved by the pair TRQ2 and at the same time the left and right elements of material Soft magnetic 13d and 13e are fixed. In addition, the first G1 magnetic lines of force between the magnetic poles of the left permanent magnets 11c and the left elements of 13d soft magnetic material are straight although their quantities magnetic flux totals are large, so that they are not generated magnetic forces to move the left elements of material soft magnetic 13d. Moreover, the second lines G2 magnetic force between the right material elements soft magnetic 13e and the magnetic poles of the magnets permanent rights 11c generate magnetic forces that push the permanent magnets rights 11c towards the right elements of soft magnetic material 13e, due to the synergistic action of its grade of curvature and the total amounts of its magnetic flux, so that the outer rotor 11 is moved in one direction (upwards as seen in figure 9) opposite to the direction in which it moves the inner rotor 12, turning towards a position represented in the Figure 9 (c).

Then, during the rotation of the outer rotor 11 from the position represented in Figure 9 (b) towards the position shown in figure 9 (c), the inner rotor 12 it is turned towards a position represented in figure 9 (d). Together with the rotation of the inner rotor 12, the permanent magnets 12c are still closer to the material rights elements soft magnetic 13e, and the second magnetic lines G2 of force between permanent magnets 12c and permanent permanent magnets 11c increase in the total amounts of its magnetic flux and they decrease in their degree of curvature, so that forces are generated Magnets that push the permanent permanent magnets 11c towards the right elements of soft magnetic material 13e by the synergistic action of the degree of curvature of the second lines G2 magnetic force and total amounts of its flow magnetic. On the other hand, first magnetic lines are generated G1 curved force between the magnetic poles of the magnets left permanent 11c and the left elements of material 13d soft magnetic, and magnetic forces are generated that push the left permanent magnets 11c towards the elements left of soft magnetic material 13d by synergistic action of the degree of curvature of the first magnetic lines G1 of strength and total amounts of its magnetic flux. But nevertheless, the magnetic forces generated by the first magnetic lines G1 strengths are considerably weaker than forces magnetic generated by the second magnetic lines G2 of force. As a result, the outer rotor 11 is moved by a magnetic force corresponding to the difference between the forces previous magnetic in the opposite direction to the direction of inner rotor rotation 12.

So when the inner rotor 12 and the rotor outside 11 are placed in a positional relationship represented in figure 9 (d), the magnetic forces generated by the first magnetic lines G1 of force between the elements Left 13d soft magnetic material and magnetic poles of the left permanent magnets 11c, and the magnetic forces generated by the second magnetic lines G2 of force between the Right elements of soft magnetic material 13e and poles magnetic permanent magnet right 11c are balanced, so that the outer rotor 11 is placed temporarily in an un powered state.

From this state, when the rotor interior 12 rotates to a position shown in the figure 10 (a), the generation status of the first lines magnetic force G1 is changed to form magnetic circuits as depicted in figure 10 (b). This makes the magnetic forces generated by the first magnetic lines G1 force stop acting by pushing permanent magnets left 11c towards the left elements of magnetic material soft 13d, and therefore the right permanent magnets 11c are pushed towards the right elements of soft magnetic material 13e by the magnetic forces generated by the second lines magnetic force G2, whereby the outer rotor 11 is moved to a position represented in figure 10 (c) in the direction opposite to the direction of rotation of the inner rotor 12.

Then, when the inner rotor 12 rotates from the position represented in figure 10 (c) slightly towards  below, as seen in the figure, the first magnetic lines G1 of force between the left elements of magnetic material soft 13d and the magnetic poles of the permanent magnets left 11c generate magnetic forces that pull the magnets left permanent 11c towards the left elements of 13d soft magnetic material by the synergistic action of the degree of curvature of the first magnetic lines G1 of force and the total amounts of its magnetic flux, inversely as above, so that the outer rotor 11 is moved in the direction opposite to the direction of rotation of the inner rotor 12. When the inner rotor 12 rotates further down, as seen in the figure, the outer rotor 11 is moved by the magnetic force corresponding to the difference between magnetic forces generated by the first magnetic lines G1 of force and the magnetic forces generated by the second magnetic lines G2 of force, in the opposite direction to the direction of rotation of the inner rotor 12. After that, when the magnetic forces generated by the second magnetic lines G2 of force stop act, the outer rotor 11 is moved by magnetic forces generated by the first magnetic lines G1 of force only, in the opposite direction to the direction of rotation of the rotor interior 12.

As described above, along with the rotation of the inner rotor 12, the magnetic forces generated by the first magnetic lines G1 of force between the elements Left 13d soft magnetic material and magnets permanent left 11c, the magnetic forces generated by the second magnetic lines G2 of force between the elements 13e soft magnetic material rights and permanent magnets 11c rights, and the magnetic force corresponding to the difference between the previous magnetic forces act alternately in the outer rotor 11, whereby the outer rotor 11 is moved in the opposite direction to the direction of rotation of the inner rotor 12. Therefore, it is possible to transmit the TRQ2 torque introduced in the inner rotor 12 to the outer rotor 11. In this case, as depicted in figure 8 (c), the outer rotor 11 rotates to the same speed as the inner rotor 12 in the opposite direction to its direction of rotation, so -V1 = V2, that is IV1I = IV2I. As described above, the inner rotor 12 rotates to  the same speed as the outer rotor 11 in the opposite direction to its direction of rotation, and therefore to the extent that the TRQ2 torque introduced in the inner rotor 12 assumes a value inside of the torque capacity range of the transmission system of magnetic power 1, the TRQ2 torque is transmitted to the outer rotor 11 as is. That is, TRQ2 = TRQ1.

Moreover, also when the rotor intermediate 13 is fixed, and the TRQ1 torque is introduced into the rotor outer 11, as before, the inner rotor 12 is moved in such a way that it rotates at the same speed as the rotor outside 11 in the opposite direction to its direction of rotation. In this case, in terms of rotational speed, V1 = -V2, that is IV1I = IV2I, and as for the pair, TRQ1 = TRQ2.

Next, a case will be described in which the three rotors 11 to 13 are turning. Figure 8 (a), to the referenced above, represents the relationship between the rotational speeds V1 to V3 of the three rotors 11 to 13, obtained when the outer rotor 11 is fixed. When the three rotors 11 to 13 rotate, just put in the figure 8 (a), the rotational speed V1 of the outer rotor 11 of such that V1 \ neq 0, and the relationship between speeds Rotational V1 to V3 is represented in Figure 8 (d). In this case, V3 = 0.5 x (V1 + V2).

Since the power transmission system magnetic 1 according to the present embodiment is used as differential, the three rotors 11 to 13 rotate during vehicle 2, and the ratio between rotational speeds V1 to V3 is the represented in figure 8 (d). It is clear by reference to Figures 8 (a) to 8 (d) that rotational speeds V1 to V3 of the three rotors 11 to 13 have the same characteristics than the rotational speeds of three elements of a planetary gear unit, so that it may consider the power transmission system magnetic 1 has the same function as the gear unit planetariums, and performs the same operation as her.

In addition, when TRQ1 \ neq 0, TRQ2 \ neq 0, and TRQ3 \ neq 0, the pairs of the three rotors 11 to 13 meet the ratio of TRQ1 = TRQ2, and TRQ3 = TRQ1 + TRQ2. More specifically, the TRQ3 torque introduced in intermediate rotor 13 is divided into two and distributes to the outer rotor 11 and the inner rotor 12. It should be indicate that, inversely to the power transmission system magnetic 1 according to the present embodiment, when the outer rotor 11 and the inner rotor 12 are used as the torque input side and the intermediate rotor 13 also as the torque output side, is meets the relationship of TRQ3 = TRQ1 + TRQ2.

As described above, according to magnetic power transmission system 1 of the present realization, given that the pair introduced in any of the three rotors 11 to 13 is transmitted to one or the other two rotors by magnetic forces, it is possible to perform the same operation of torque transmission than that performed by the gear unit planetarium, using magnetic forces. Therefore in a unit to carry out the same torque transmission operation that the one executed by the planetary gear unit, is possible to ensure peculiar advantageous effects of the system of magnetic power transmission, including the no requirement of a lubricating structure, and the absence of danger of generating slack or dust on the contact portions. In addition, when transmits torque, magnetic paths are formed using all permanent magnets left and right 11c and 11c, the elements Left 13d soft magnetic material, permanent magnets 12c, and the right elements of soft magnetic material 13e, of so that it is possible to efficiently secure the areas of the magnetic paths As a result, while maintaining the advantageous effects obtained by performing power transmission by magnetic forces, it is possible to improve the efficiency of torque transmission and torque transmission capacity, in comparison with conventional power transmission system magnetic forming magnetic paths using only part of The magnetic poles.

In addition, the power transmission system magnetic 1 can be performed by a relatively construction simple that has the outer rotor 11 including the rows of magnets permanent left and right, the inner rotor 12 including the row of permanent magnets, and intermediate rotor 13 including the left and right elements of soft magnetic material, of so that manufacturing costs can be reduced in comparison with the conventional magnetic power transmission system provided with magnetic teeth that have a complicated shape.

It should be noted that, although the first embodiment is an example in which the transmission system of magnetic power according to the present invention is applied to differential for a vehicle, this is not limiting, but the magnetic power transmission system according to the present invention can be applied to torque transmission systems various industrial devices and devices, in particular a torque transmission system required to perform the operation which holds the planetary gear unit. For example, The magnetic power transmission system according to the present invention can be applied to a power transmission system for a wind turbine

In addition, although the first embodiment is a example in which the left and right permanent magnets 11c and 11c, permanent magnets 12c, left and right elements of soft magnetic material 13d and 13e are arranged in it number at the same step, this is not limiting, but you can employ any suitable number and arrangement of these elements to the extent that the first magnetic lines G1 of force and the second magnetic lines G2 of force are generated in such a way so that the torque transmission can be performed properly between the three rotors 11 to 13.

For example, the elements can be arranged such that when each permanent magnet 12c is in a relationship positional with each of the left permanent magnets and right 11c and 11c, where you are slightly displaced from a line that connects the respective centers of the permanent magnets left and right 11c and 11c, one of the left elements and soft magnetic material rights 13d and 13e is in a position  between permanent magnets 11c and 12c, and the other is in a position between every two circumferentially adjacent magnets of permanent magnets 11c and permanent magnets 12c. In addition, permanent magnets 11c and 11c, permanent magnets 12c, and the left and right elements of magnetic material Soft 13d and 13e can be arranged in the same number at intervals approximately equal.

In addition, the left and right elements of soft magnetic material 13d and 13e can be arranged in it number at the same step, and the permanent magnets left and right 11c and 11c and permanent magnets 12c can be arranged in the same number at the same step, putting the number of the elements left and right of soft magnetic material 13d and 13e at a value less than the number of permanent magnets left and right 11c and 11c and permanent magnets 12c.

In addition, the left intermediate rotors and Right 23 and 23 are equally arranged, except in part. In first the left intermediate rotor will be described 23. The left intermediate rotor 23 includes a hollow cylindrical portion 23a mounted concentrically and rotatably on the axis of rotation 21a, a left wall 23b integrally formed with the cylindrical portion hollow 23a, and a gear 23c. A row of left elements of soft magnetic material is arranged at a more forward end of the left wall 23b such that it is in a position between the left row of permanent magnets of the outer rotor left 21 and the row of permanent magnets of the inner rotor left 22 in a relationship opposite to these.

The left element row of material Soft magnetic consists of m left elements of material soft magnetic 23d. The left elements of magnetic material soft 23d are arranged in the same number at the same step and at the same radial distance from the center of rotation as the magnets permanent 21c and permanent magnets 22c. In addition, the opposite side surfaces of each left element of 23d soft magnetic material have approximately the same area and shape that of the end faces of each permanent magnet 21c and each permanent magnet 22c.

According to the power transmission system magnetic 1B of the second embodiment arranged as described  previously, it is possible to obtain the same advantageous effects as those provided by the magnetic power transmission system 1 according to the first embodiment. More specifically, it is possible execute the same power transmission operation as the performed by the planetary gear unit, using the magnetic forces In addition, it is possible to efficiently ensure areas of the magnetic paths, so keeping the at the same time the advantageous effects obtained by transmitting of power through magnetic forces, it is possible to improve the torque transmission efficiency and transmission capacity of torque, compared to the conventional transmission system of magnetic power that forms magnetic paths using only part of the magnetic poles.

It should be noted that, although the system of 1B magnetic power transmission according to the second embodiment it is an example in which the six rotors 21 to 23 as the elements first to sixth mobiles are connected by the mechanism of gear, this is not limiting, but the transmission system of magnetic power according to the present invention can be arranged so that the first mobile element and the third mobile element, the second mobile element and the fourth mobile element, and the fifth mobile element and the sixth mobile element move one in relation to another in an embedded way. For example, the transmission system of magnetic power according to the present invention can be arranged so that two moving elements move relative to each other nailed by a combination of pulleys and belts.

In addition, although the transmission system of magnetic power 1B according to the second embodiment is an example in which the magnetic power transmission system has built in a way that is bilaterally symmetric except of the polarities of the magnetic poles of the permanent magnets 22c of the left and right inner rotor 22, and the arrangement of the left elements of soft magnetic material 23d and the Right elements of soft magnetic material 23e of the rotors left and right intermediate 23, this is not limiting, but The magnetic power transmission system can be built so that it is bilaterally asymmetric. For example, the left and right rotors of the outer rotors 21 and 21, the inner rotors 22 and 22, and intermediate rotors 23 and 23 can be configured so that they have different diameters one of another so that the numbers and the steps of the permanent magnets 21c, permanent magnets 22c, and magnetic elements of soft material 23d and 23e are different between the rotors left and right.

A system of magnetic power transmission 10 according to a third embodiment of the present invention. As depicted in figures 13 and 14, This 1c magnetic power transmission system is distinguished of the magnetic power transmission system 1 according to the first realization in the construction of part of the outer rotor 11, and in which includes two actuators 17 and 17, and is arranged the same as the 1 magnetic power transmission system in the others aspects. Therefore, the following description will refer mainly to different construction points, while the component elements of the power transmission system 1C magnetic, identical to those of the power transmission system  magnetic 1, are designated with identical reference numbers, and are omit its detailed description.

As depicted in the two figures, the 10 magnetic power transmission system includes rotor outside 11, and left and right actuators 17 and 17. The rotor exterior 11 includes the axis of rotation 11a, and left discs and right 11d and 11d concentric with the axis of rotation 11a. The discs left and right 11d and 11d are mounted on the axis of rotation 11a by grooving, respectively, so they are willing to so that they are relatively axially mobile with respect to the axis of rotation 11a and turn in unison with the axis of rotation 11a.

In addition, the left and right actuators 17 and 17 (magnetic force change device) have the same provision, and therefore the following description will refer to left actuator 17, by way of example. Left actuator 17 includes a body 17a, and a retractable rod 17b with respect to the body 17a. A more forward end of the rod 17b is connected to left disk 11d. This actuator 17 is connected electrically to a control system, not shown, and moves the left disk 11d between a transmission position indicated by two dotted lines and stroke in figure 13 and a position of interruption indicated by continuous lines in the figure, in response to an order signal from the control system.

Like the left actuator 17, the right actuator 17 is also electrically connected to the control system, not shown, and moves the right disk 11d between a transmission position indicated by two-point lines and trace in figure 13 and an interruption position indicated by solid lines in the figure, in response to an order signal from the control system.

In the power transmission system magnetic 1C, when the left and right disks 11d and 11d are in the transmission positions, just like the system of magnetic power transmission 1 described above according to the first embodiment, the torque is transmitted between the three rotors 11 to 13. For example, when the TRQ3 torque is introduced into the rotor intermediate 13, the TRQ3 torque is transmitted to the outer rotor 11 and the inner rotor 12, respectively.

From the previous state, when the disks left and right 11d and 11d are moved from the positions of transmission to interrupt positions by actuators left and right 17 and 17, the magnetic resistance is increased between each permanent magnet 12c and the permanent magnets 11c and 11c of the left and right discs 11d and 11d and the total amounts of its magnetic flux. According to the decrease of the total amounts of magnetic flux, the capacity of torque transmission between the three rotors 11 to 13. Then, when the left and right discs 11d and 11d are moved at respective interruption positions, the total amounts of magnetic flux decrease greatly, leading to a state in which no torque is transmitted between the three rotors 11 to 13.

As described above, according to 1C magnetic power transmission system of the third realization, it is possible to operate the left and right disks 11d and 11d between the transmission positions and the positions of interruption by actuators 17 and 17 at will. In this case, when the left and right discs 11d and 11d remain in the transmission positions, it is possible to obtain the same effects advantageous than those provided by the transmission system of magnetic power 1 according to the first embodiment. Also moving the left and right discs 11d and 11d from the positions of transmission to interrupt positions, it is possible change the torque transmission capacity between the three rotors 11 to 13 at will. In particular, when the disks left and right 11d and 11d are moved to interrupt positions, it is possible to interrupt torque transmission between the three rotors 11 to 13.

It should be noted that the method of changing the torque transmission capacity between the three rotors 11 to 13 e interrupting torque transmission is not limited to the method before described according to the third embodiment, but the next method. For example, a power transmission system magnetic 1D as shown in figure 15 can be arranged so that the left disk 11d is only moved from the transmission position towards the interrupted position by the actuator 17 (magnetic force change device). With this arrangement, it is possible to change the torque transmission capacity between the three rotors 11 to 13.

In addition, a power transmission system magnetic 1E as shown in figure 16 can be arranged so that short circuit elements 18 indicated by shaded in the figure, and an actuator, not shown, for move the short circuit elements 18, and the elements of short circuit 18 are inserted between permanent magnets 11c and 11c and between the permanent magnets 12c and 12c by the actuator, for short circuit the magnetic circuits. With this arrangement, it is possible to interrupt the torque transmission between three rotors 11 to 13. It should be noted that in this example, the short circuit elements 18 and the actuator correspond to magnetic force change devices.

A system of 1F magnetic power transmission according to a fourth embodiment of the present invention with reference to figure 17 and figure 18. As shown in the figures, this transmission system 1F magnetic power is applied to the system differential of drive for vehicle 2, like said system of magnetic power transmission 1 according to the first embodiment. Since the vehicle 2 is generally arranged equally to the vehicle 2 to which the first embodiment applies, then only the different points of the first one will be described embodiment, while identical component elements are designate with identical reference numbers, and their detailed description.

The magnetic power transmission system 1F includes a small diameter rotor 31, a large rotor diameter 32, and a rotor of intermediate diameter 33, and the three rotors 31 to 33 are supported by large number of bearings radial and thrust bearings (of which none are shown in the figures) so that they hardly change in relationships mutual positions in the direction of the rotational axis and the radial direction, and are arranged so that they are rotating around the same rotational axis in relation to each other.
